進階 FHIR 搜尋功能

本頁說明如何使用 projects.locations.datasets.fhirStores.fhir.search 方法提供的進階查詢功能，搜尋 FHIR 資源。本指南假設您已熟悉「搜尋 FHIR 資源」的內容。

FHIR 軟體包範例

本頁面的範例會使用提供的 JSON FHIR 套件，顯示進階 FHIR 搜尋功能的結果。將 r4_bundle.json 檔案儲存到電腦，以便在範例中使用。

執行範例 FHIR 軟體包

如要在 FHIR 存放區中執行範例 FHIR 軟體包，請參閱「執行軟體包」。FHIR 儲存庫必須具備下列設定：

將 enableUpdateCreate 設為 true。
將 version 設為 R4。

字串搜尋修飾符

字串搜尋預設為前置字串比對，且不區分大小寫和重音符號，方法是摺疊至標準 Unicode NFC 形式。系統會忽略標點符號和多餘的空白字元。

可用的修飾符如下：

:contains 會比對字串中任何位置含有指定值的資源，例如 name:contains=eve 會比對 Evelyn 和 Severine。
:exact 會比對整個字串，包括大小寫和重音符號，例如 name:exact=Eve 不會比對 eve 或 Evelyn。

展開下列部分，查看使用搜尋字串修飾符的範例：

使用任何要求資料之前，請先替換以下項目：

PROJECT_ID：您的 Google Cloud 專案 ID
LOCATION：父項資料集的位置
DATASET_ID：FHIR 儲存庫的父項資料集
FHIR_STORE_ID：FHIR 儲存庫 ID

如要傳送要求，請選擇以下其中一個選項：

curl

下列範例使用 Patient?name:contains=eve 查詢。

執行下列指令：

curl -X GET \
     -H "Authorization: Bearer $(gcloud auth print-access-token)" \
     "https://healthcare.googleapis.com/v1/projects/PROJECT_ID/locations/LOCATION/datasets/DATASET_ID/fhirStores/FHIR_STORE_ID/fhir/Patient?name:contains=eve"

PowerShell

下列範例使用 Patient?name:contains=eve 查詢。

執行下列指令：

$cred = gcloud auth print-access-token
$headers = @{ "Authorization" = "Bearer $cred" }

Invoke-WebRequest `
    -Method GET `
    -Headers $headers `
    -Uri "https://healthcare.googleapis.com/v1/projects/PROJECT_ID/locations/LOCATION/datasets/DATASET_ID/fhirStores/FHIR_STORE_ID/fhir/Patient?name:contains=eve" | Select-Object -Expand Content

數字、日期和數量的比較子和精確度

在數字或日期搜尋中使用的值取決於參數值的精確度。舉例來說，數字 7.00 的隱含範圍為 6.995 (含) 到 7.005 (不含)。日期 2015-08-12 的範圍為包含 2015-08-12T00:00:00 但不含 2015-08-13T00:00:00。

精確度會影響等式比較傳回的結果。舉例來說，資源中的 7.03 值會與 value=7.0 的搜尋結果相符，但不會與 value=7.00 的搜尋結果相符。

FHIR 中所有具有臨床意義的浮點值，都會以 Decimal 和 Quantity 等類型表示，這些類型會記錄儲存值的精確度。但有少數欄位會使用簡單的整數，例如表示序列中的位置，而對這些欄位進行搜尋時，系統會比對確切的數值。

下列前置字元適用於與單一值進行的數值比較。如未指定任何前置字元，則預設為 eq。

eq：等於，確切的儲存值位於參數值精確度定義的範圍內
ne：不等於，與 eq 相反
gt：確切的儲存值大於確切的參數值
lt：確切儲存的值小於確切參數值
ge：確切儲存的值大於或等於確切參數值
le：確切儲存的值小於或等於確切參數值

日期值會根據值的具體程度 (一年、一個月、一天) 隱含範圍。其他資料類型 (例如「範圍」和「週期」) 包含明確的上下限。以下前置字元適用於範圍比較。如未指定任何前置字元，則預設為 eq。

eq：等於，參數值的範圍完全包含目標的範圍
ne：不等於，與 eq 相反
gt：大於，參數值以上的範圍與目標範圍重疊
lt：小於，參數值以下的範圍與目標範圍重疊
ge：大於或等於
le：小於或等於
sa：參數值的範圍從目標範圍之後開始
eb：參數值範圍在目標範圍之前結束

使用任何要求資料之前，請先替換以下項目：

PROJECT_ID：您的 Google Cloud 專案 ID
LOCATION：父項資料集的位置
DATASET_ID：FHIR 儲存庫的父項資料集
FHIR_STORE_ID：FHIR 儲存庫 ID

如要傳送要求，請選擇以下其中一個選項：

curl

下列範例使用 _lastUpdated=gt2018-01-01 查詢，搜尋 _lastUpdated 值大於 (gt)2018-01-01 的病患資源。

執行下列指令：

curl -X GET \
     -H "Authorization: Bearer $(gcloud auth print-access-token)" \
     "https://healthcare.googleapis.com/v1/projects/PROJECT_ID/locations/LOCATION/datasets/DATASET_ID/fhirStores/FHIR_STORE_ID/fhir/Patient?_lastUpdated=gt2018-01-01"

PowerShell

下列範例使用 _lastUpdated=gt2018-01-01 查詢，搜尋 _lastUpdated 值大於 (gt)2018-01-01 的病患資源。

執行下列指令：

$cred = gcloud auth print-access-token
$headers = @{ "Authorization" = "Bearer $cred" }

Invoke-WebRequest `
    -Method GET `
    -Headers $headers `
    -Uri "https://healthcare.googleapis.com/v1/projects/PROJECT_ID/locations/LOCATION/datasets/DATASET_ID/fhirStores/FHIR_STORE_ID/fhir/Patient?_lastUpdated=gt2018-01-01" | Select-Object -Expand Content

查詢 _lastUpdated=gt2018-01-01 會傳回自 2018 年 1 月 1 日起更新的病患資源。如果您是在該日期之後建立 FHIR 儲存庫中的所有資源，伺服器就會傳回所有資源。如要查看部分資源，請將日期變更為某些資源上次更新後的時間。

權杖搜尋

如果值不是任意字串，而是命名系統中的實體，就適用權杖搜尋參數。權杖參數的字串比對結果必須完全相符。

大多數權杖搜尋適用於含有 system 的複雜資料類型，該 system 是 URI，指出 code 值取自的命名系統。這些搜尋支援下列值語法：

[parameter]=[code] 符合 code 值，不論 system 為何
[parameter]=[system]|[code] 必須同時符合指定的 system 和 code
如果 system 值為空白，則 [parameter]=|[code] 會與 code 相符
[parameter]=[system]| 符合具有指定 system 值的任何 code

有幾種修飾符會觸發替代符記搜尋功能：

:not 會否定符記搜尋的比對條件
:text 對與程式碼相關聯的 text 或 display 欄位執行字串搜尋 (而非完全比對)，而不是程式碼值本身
:above 只會採用 [system]|[code] 形式的參數，並比對資源，其中資源中的程式碼會包含查詢參數。如要使用這個修飾符，指定的 system 必須以 CodeSystem 資源的形式存在於 FHIR 儲存庫中。
:below 與 :above 類似，但如果資源中的程式碼由查詢參數涵蓋，就會相符。
:in 會使用參照參數語法接收單一參數，例如 code:in=ValueSet/1234。參照必須參照同一 FHIR 儲存庫中的 ValueSet 資源。修飾符會比對參照 ValueSet 中的任何程式碼。
:not-in 會否定 :in 的條件

權杖搜尋也適用於布林值和 URI 欄位，以及只允許完全比對的特定字串欄位。在這些情況下，唯一參數格式為 [parameter]=[value]。

權杖搜尋範例

REST

使用任何要求資料之前，請先替換以下項目：

PROJECT_ID：您的 Google Cloud 專案 ID
LOCATION：父項資料集的位置
DATASET_ID：FHIR 儲存庫的父項資料集
FHIR_STORE_ID：FHIR 儲存庫 ID

如要傳送要求，請選擇以下其中一個選項：

curl

下列範例使用 Patient?_tag=tag-system|tag2 查詢，搜尋具有指定 system 和 code 的病患資源。

執行下列指令：

curl -X GET \
     -H "Authorization: Bearer $(gcloud auth print-access-token)" \
     "https://healthcare.googleapis.com/v1/projects/PROJECT_ID/locations/LOCATION/datasets/DATASET_ID/fhirStores/FHIR_STORE_ID/fhir/Patient?_tag=tag-system|tag2"

PowerShell

下列範例使用 Patient?_tag=tag-system|tag2 查詢，搜尋具有指定 system 和 code 的病患資源。

執行下列指令：

$cred = gcloud auth print-access-token
$headers = @{ "Authorization" = "Bearer $cred" }

Invoke-WebRequest `
    -Method GET `
    -Headers $headers `
    -Uri "https://healthcare.googleapis.com/v1/projects/PROJECT_ID/locations/LOCATION/datasets/DATASET_ID/fhirStores/FHIR_STORE_ID/fhir/Patient?_tag=tag-system|tag2" | Select-Object -Expand Content

搜尋遺漏值

您可以在任何搜尋參數中使用搜尋修飾符 :missing，根據指定欄位中是否有任何值進行比對。舉例來說，Patient?gender=unknown 會比對明確包含性別 unknown 列舉值的資源，但由於這個欄位並非必填，因此可能會有其他資源完全未填入這個欄位。這類資源可由 Patient?gender:missing=true 比對。反之，Patient?gender:missing=false 會比對明確填入這個欄位的任何資源。

文字搜尋

使用 _content 搜尋參數時，如果未指定 FHIR 資源類型，系統會將其視為已淘汰。使用 _content 進行搜尋時，您必須透過下列其中一種方式指定 FHIR 資源類型：

在 /fhir/ 後的 HTTP 路徑中：

https://healthcare.googleapis.com/v1/.../fhirStores/my-fhir-store/fhir/Patient?_content=Smith%20|%20Mountain%20View

在 HTTP 路徑中使用 _type 參數：

https://healthcare.googleapis.com/v1/.../fhirStores/my-fhir-store/fhir?_type=Patient&_content=Smith%20|%20Mountain%20View

如果未提供 FHIR 資源類型，搜尋查詢的結果會視 FHIR 儲存庫是否已啟用 defaultSearchHandlingStrict 而定：

defaultSearchHandlingStrict 已啟用：搜尋查詢會傳回錯誤。
defaultSearchHandlingStrict 已停用：搜尋查詢會忽略 _content 參數中的資訊。

如果欄位是資源上任何搜尋參數的目標，特殊搜尋參數 _content 會對字串型欄位執行文字比對 (不包括數字、日期或列舉欄位)。根據預設，_content 會比對包含查詢中所有字詞的資源，並支援其他運算子：

| 是 OR 運算子，例如 abc | def | ghi xyz 會比對包含 xyz 和一或多個 abc def ghi 的資源。
- 是 NOT 運算子，例如 abc -def 會比對包含 abc 但不包含 def 的資源。

比對依據是完整字詞，不比對子字串或非英數字元。字詞順序沒有影響。相符字詞可分布在資源的多個欄位中。

參數 _text 只會對「敘述」欄位執行相同類型的比對，這個欄位應包含資源內容的清楚易懂摘要。Cloud Healthcare API 不會自動產生這份摘要，但如果用戶端在建立或更新資源時填入這項資料，API 就會支援 _text 搜尋參數。

複合搜尋參數

使用多個查詢參數搜尋時，有時個別搜尋參數與 AND 結合後，會比對出非預期的結果。複合搜尋參數是一種特殊的搜尋參數，可解決這個問題。

舉例來說，Observation 資源的 component 欄位可能包含多個值，每個值都包含一組 code 和 value。搜尋 Observation?component-code=8867-4&component-value-quantity=lt50 時，如果資源有一個元件包含 8867-4 的 code，且另一個元件包含小於 50 的 value，就會相符。這項搜尋無法用於限制在同一元件中比對這兩個值。

複合搜尋參數會定義新的參數，結合另外兩個搜尋參數，並定義兩者都必須相符的巢狀層級。在查詢中，這兩個值會以 $ 聯結。舉例來說，Observation 具有複合參數 component-code-value-quantity，可透過搜尋 Observation?component-code-value-quantity=8867-4$lt50，將先前的範例限制為單一元件。這些參數是由 FHIR 規格定義，並非適用於所有搜尋參數組合。

複合搜尋參數不允許使用修飾符。

與所有搜尋參數一樣，如要瞭解 Cloud Healthcare API 支援哪些複合參數，請參閱功能聲明或 FHIR 一致性聲明。

鏈結搜尋

鏈結搜尋可讓搜尋在查詢內容的參照中移動。鏈結搜尋的基本語法如下：

[reference parameter]:[resource type].[inner search parameter]=[inner value]

如果參照參數只參照一種資源類型，則可以省略 :[resource type]，產生以下結果：

[reference parameter].[inner search parameter]=[inner value]

舉例來說，Observation 具有參照搜尋參數 subject，可能指向 Group、Device、Patient 或 Location。如要找出名稱開頭為「Joe」的 Patient，並取得該 Patient 的 subject，可以搜尋 Observation?subject:Patient.name=Joe。Observations

如果查詢有多個鏈結參數，系統會分別評估每個鏈結。舉例來說，Patient?general-practitioner.name=Joe&general-practitioner.address-country=Canada 會比對具有兩個 general-practitioner 參照的 Patient，一個名為「Joe」，另一個的地址位於加拿大。沒有語法可將這些子句分組，只比對來自加拿大的 Joe。

鏈結搜尋可以遞迴處理其他鏈結或反向鏈結，例如 Observation?subject:Patient.organization.name=Acme 會比對參照 subject 的 Observation，而 subject 參照的 organization 具有 Acme 的 name。

連鎖搜尋範例

REST

使用任何要求資料之前，請先替換以下項目：

PROJECT_ID：您的 Google Cloud 專案 ID
LOCATION：父項資料集的位置
DATASET_ID：FHIR 儲存庫的父項資料集
FHIR_STORE_ID：FHIR 儲存庫 ID

如要傳送要求，請選擇以下其中一個選項：

curl

以下範例使用 Observation?subject:Patient.name=Christopher 查詢，傳回所有具有 subject 的「觀測」項目，而 subject 是名稱開頭為 Christopher 的 Patient。

執行下列指令：

curl -X GET \
     -H "Authorization: Bearer $(gcloud auth print-access-token)" \
     "https://healthcare.googleapis.com/v1/projects/PROJECT_ID/locations/LOCATION/datasets/DATASET_ID/fhirStores/FHIR_STORE_ID/fhir/Observation?subject:Patient.name=Christopher"

PowerShell

以下範例使用 Observation?subject:Patient.name=Christopher 查詢，傳回所有具有 subject 的「觀測」項目，而 subject 是名稱開頭為 Christopher 的 Patient。

執行下列指令：

$cred = gcloud auth print-access-token
$headers = @{ "Authorization" = "Bearer $cred" }

Invoke-WebRequest `
    -Method GET `
    -Headers $headers `
    -Uri "https://healthcare.googleapis.com/v1/projects/PROJECT_ID/locations/LOCATION/datasets/DATASET_ID/fhirStores/FHIR_STORE_ID/fhir/Observation?subject:Patient.name=Christopher" | Select-Object -Expand Content

反向鏈結搜尋

反向鏈結搜尋會根據參照資源的其他資源條件，比對資源。反向鏈結搜尋的語法如下：

_has:[resource type]:[reference parameter]:[search parameter]=[value]

舉例來說，Appointment 資源具有參照 Patient 資源的搜尋參數 patient。如要找出 Appointment 資源在 2020-04-01 日期參照的所有 Patient 資源，請使用 Patient?_has:Appointment:patient:date=eq2020-04-01。

反向鏈結可與其他鏈結或反向鏈結遞迴，例如 Practitioner?_has:Encounter:practitioner:_has:Claim:encounter:created=eq2020-04-01 會比對 Practitioner P (如有 Encounter E 和 Claim C，且 C 的建立日期為 2020-04-01、C 透過 encounter 參照 E，而 E 透過 practitioner 參照 P)。

反向鏈結搜尋範例

REST

使用任何要求資料之前，請先替換以下項目：

PROJECT_ID：您的 Google Cloud 專案 ID
LOCATION：父項資料集的位置
DATASET_ID：FHIR 儲存庫的父項資料集
FHIR_STORE_ID：FHIR 儲存庫 ID

如要傳送要求，請選擇以下其中一個選項：

curl

下列範例使用 Patient?_has:Procedure:patient:date=eq2008-03-07 查詢。

執行下列指令：

curl -X GET \
     -H "Authorization: Bearer $(gcloud auth print-access-token)" \
     "https://healthcare.googleapis.com/v1/projects/PROJECT_ID/locations/LOCATION/datasets/DATASET_ID/fhirStores/FHIR_STORE_ID/fhir/Patient?_has:Procedure:patient:date=eq2008-03-07"

PowerShell

下列範例使用 Patient?_has:Procedure:patient:date=eq2008-03-07 查詢。

執行下列指令：

$cred = gcloud auth print-access-token
$headers = @{ "Authorization" = "Bearer $cred" }

Invoke-WebRequest `
    -Method GET `
    -Headers $headers `
    -Uri "https://healthcare.googleapis.com/v1/projects/PROJECT_ID/locations/LOCATION/datasets/DATASET_ID/fhirStores/FHIR_STORE_ID/fhir/Patient?_has:Procedure:patient:date=eq2008-03-07" | Select-Object -Expand Content

在搜尋結果中加入其他資源

_include 和 _revinclude 參數會要求搜尋結果包含與直接符合查詢的資源 (「主要結果」) 相關的其他資源 (「納入的資源」)。與分別發出一連串要求來擷取這些額外資源相比，使用這些參數的效率更高。在搜尋傳回的 searchset 組合中，這些參數新增的資源會標示 entry.search.mode = include，與標示 entry.search.mode = match 的主要結果有所區別。

使用 _include 正向納入會新增主要結果參照的資源和資源版本，使用 _revinclude 反向納入則會新增參照主要結果的資源。要追蹤的參照是由搜尋參數的名稱指定，且只有可做為搜尋參數的參照欄位，才能以這種方式使用。

_include 和 _revinclude 的參數格式相同，都是以 : 分隔兩個或三個值。第一個值是參照來源的資源類型，第二個值是搜尋參數名稱，第三個值 (選用) 則會在參照可指向多個類型時，將資源類型限制為單一類型。

例如：

MedicationRequest?_include=MedicationRequest:subject 會搜尋 MedicationRequest 資源，並針對傳回的每個資源，傳回 subject 參照的目標，這可能是 FHIR 規格中定義的 Group 或 Patient。
MedicationRequest?_include=MedicationRequest:subject:Patient 類似，但只會傳回 Patient 資源的 subject 參照。
MedicationRequest?_revinclude=Provenance:target 會搜尋 MedicationRequest 資源，並針對傳回的每個資源，傳回 Provenance 上的 target 參照所指的相符資源。Provenance

修飾符 :iterate 會導致 _include 進行疊代評估。這個修飾符可以追蹤所含結果的額外參照層級，或追蹤遞迴結構，例如參照另一個 Observation:derived-from 的 Observation。

遞迴深度限制為兩層：頂層和兩個子層。舉例來說，假設您有下列參照序列：

透過 Patient.generalPractitioner 欄位參照 PractitionerRole 資源的 Patient 資源。
PractitionerRole 資源會透過 PractitionerRole.practitioner 欄位參照 Practitioner 資源。
從業人員資源會透過 Practitioner.qualification.issuer 欄位參照機構資源。

以下範例顯示參照順序。由於超出最多兩層的限制，因此第 3 層的機構資源不會納入搜尋結果。

Patient (Level 0)
  - Patient.generalPractitioner -> PractitionerRole (Level 1)
    - PractitionerRole.practitioner -> Practitioner (Level 2)
      - Practitioner.organization -> Organization (Level 3)

下列其他範例說明 :iterate 修飾符的行為：

Observation?_include:iterate=Observation:derived-from:Observation 會搜尋 Observation 資源，並遞迴追蹤相符 Observation 資源和所含資源的衍生自參照。
MedicationRequest?_revinclude=Provenance:target&_include:iterate=Provenance:agent 會搜尋 MedicationRequest 資源，包括含有 target 的 Provenance 資源 (位於這個結果集中)，然後也包括透過這些 Provenance 資源的 agent 參數參照的資源。

萬用字元 * 表示應納入所有可做為搜尋參數的參照。您可以在 _include 中使用 * 萬用字元做為第一個也是唯一的引數，或取代標準 _include 中的搜尋參數名稱，其中選用的第三個值會將資源類型限制為單一類型，與原始行為相同。

例如：

Observation?_include=* 會搜尋 Observation 資源，並為每個資源傳回所有參照資源。
Observation?_include=Observation:* 等同於上述內容。
MedicationRequest?_include=MedicationRequest:*:Patient 會傳回每個 MedicationRequest 資源的所有 Patient 資源參照。

伺服器會重複資料刪除資源，因此即使資源出現在多個參照中，每個結果頁面也只會包含一個資源副本。如果主要結果與隨附資源相關，隨附資源就會顯示在每個結果頁面上。

管理內含資源數量

使用 _include 和 _revinclude 參數加入其他資源時，請注意下列事項：

內含資源不會計入網頁大小。這些資源不會計入 Bundle.total，且可能會導致傳回的資源數量大於指定的 _count 參數。
由於納入的資源不會計入網頁大小，請謹慎使用 _include 和 _revinclude 參數，以免產生大量結果。結果過大可能會導致逾時或發生錯誤。如果您預期會有很多納入的結果，請考慮使用較小的 _count 值，限制主要結果的數量。避免追蹤一對多關係，其中關係的多方不受限制。
個別 _revinclude 參數最多可新增 100 個額外資源。如果參照主要結果的資源可能超過 100 個，請採取下列任一做法：
- 使用分頁大小和分頁參數，透過個別的搜尋查詢要求擷取更多結果。
- 使用內含資源開始搜尋：
  
  假設 ID 為 1234 的 Encounter 資源有數百個 Observation 資源。使用 _revinclude (從 Encounter 開始) 搜尋這些 Observation 資源時，傳回的回應會超過 100 個額外資源的限制：
```
fhir/Encounter?_id=123&_revinclude=Observation:encounter
```
  請改為搜尋 Observation 資源，並使用 _include 納入相關的 Encounter：
```
fhir/Observation?encounter=123&_include=Observation:encounter
```
  這個方法會篩選 Observation 資源，只保留與 Encounter 相關的資源，並只擷取一次 Encounter 資源。

限制搜尋結果中傳回的欄位

_elements 參數可讓用戶端要求只傳回每個搜尋結果的欄位子集，藉此省略不必要的資料，減少回應大小。這個參數接受以半形逗號分隔的資源基本元素名稱清單，例如 Patient?_elements=identifier,contact,link。只有這些欄位及其子項會納入傳回的資源。如果回應中的資源因這個參數而有所變更，就會包含 meta.tag 值 SUBSETTED，表示資源不完整。

Cloud Healthcare API 對 _summary 參數的支援有限，這個參數會提供預先定義的資源欄位子集，類似於 _elements：

_summary=text 只會傳回 text、id 和 meta 頂層欄位
_summary=data 會移除 text 欄位，並傳回所有其他欄位

進階 FHIR 搜尋功能 透過集合功能整理內容 你可以依據偏好儲存及分類內容。
